1 High Temperature 48 hours at a temperature of 160° F (71°C) followed by 30 minutes at 200F (93C). This under a pressure of 5.5 psia (0.35 atm) and relative humidity not exceeding 15% 2. Low temperature Four hours at a temperature of 0F (-18C) 3. Temperature pressure Chamber pressure maximun of 1.47 x 10exp-5 psia (10exp-6 atm) with temperature raised to 160F (71C). The temperature shall then be lowered to 0°F (-18C) in 45 minutes and raised again to 160F in 45 minutes. Fifteem more such cycles shall be completed. 4. Relative humidity A total time of 240 hours at tempeartures varying between 68F and 160F (20C and 71C) in a relative humidity of at least 95%. The steam used must have a pH value between 6.5 and 7.5 5. Oxygen atmosphere The test item shall be placed in an atmosphere of 100% oxygen at a pressure of 5.5 psia (0.35atm) for 48 hours. Performance outside of specification tolerance, visible burning, creation of toxic gases, obnoxious odours or deterioration of seals and lubricants shall constitute a failure to pass this test. The ambient temperature shall be maintained at 160°F (71°C) 6. Shock Six shocks of 40g's each 11 miliseconds in duration, in six different directions. 7. Acceleration The equipment shall be accelerated linearly from 1g to 7.25 g within 333 seconds, along an axis parallel to the longitudinal spacecraft axis. 8. Decompression Ninety minutes in a vacuum of 1.47 x 10E-5 psia (10 E-6 atm) at a temperature of 160F (71C) and 30 minutes at a 200F (93C) 9. High Pressure The equipment to be subjected to a pressure of 23.5 psia (1.6 atm) for a minimum period of one hour. 10. Vibration Three cycles of 30 minutes (lateral, horizontal, vertical, the frequency varying from 5 to 2000 cps and back to 5 cps in 15 minutes. Average acceleration per impuls must be at least 8.8g. 11. Acoustic noise 130 dB over a frequency range from 40 to 10000 HZ, duration 30 minutes. |
